COIN-DETECTOR.

Specification of Letters Patent.

Patented. Mar. 26, i912.

Application led August 26,'1911. Serial No. 646,114.

'H Be it known that I, ARTHUR E. MARSH, al citizen. of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented new and Vuseful lmprovements in Coin-Detectors, of- -which the following is a specification.

' The inventionrelates to coin chutes, and

` more particularly to the class of coin detectors forcoin chutes designed for use in coin controlled delivery machines., l

The primary object ofthe invention is .the provi-sion of a'devicey of uthis character in which any coin of a predetermined denomination and possessing the standard weight will be permitted to be delivered from the chute within themachine for effecting the actuation of the same, but should a spurious or dummy coin be inserted in the chute of the machine vof less weight than the standard coin, it will be ejected from the chute, or should a slug of heavier weight than the standard coin be introduced into the chute, it willbe deflected from the regular course therein, so as to be ineffective in operatin ture.

With these and. otherobjects in view, the

invention consists in the construction, com'-v bination and arrangement of parts, as will be hereinafter more fully' described, illustrated in the accompanying drawings,and

pointed out in the claims hereunto appended.

y In the drawings: Figure 1 is a-fragmentary vertical longitudinal sectional view through a coin controlled vending apparatus, showing the coiny chute disposed therein and' also the coin detector constructed in accordance with the invention. Fig. 2 is a sectional view on .the line 2 2 of Fig. 1, with the coin detector in normal position. Fig. 3 is a similar view, showing the coin detector tilted. Fig. LLis a sectional view on A the line L1,-4 of Fig. 1.

with a coin chute Acolumn 7, between the side walls of Whlch 1s arrangeda rearwardly 1nvclined runway 8 for the coins inserted through the` slit 6`into thecolumn, so that the said coins will be directed onto a coin detector, presently described.

The coin detector comprises a forwardly inclined side tilting platform 9 which is arranged below the runwa 8 within t'he column 7, the platform being Iformed at its rear end with a medial knife edge pivotk 10 journaled in a bearing 11 fixed to the `rear wall of the column 7, while at its front end, at one longitudinal edge thereof, is formed a .for-

wardly directed knife edge fulcrum or pivot 12, the same being journaled in a bearin 13 Xed to the front wallof the column 7, t us enabling the said platform to possess-a tilting action on a diagonal axis, whereby its rear ,port-ion will have a short leverage, while its forward portion will have a long leverage, for a purpose presently described.

Formed contiguous to the front knife edge pivot 12 and projecting laterally therefrom is a threaded weight arm 14, on which is adjustably mounted a weight. kcarrying element 15 providedwith a depending weight key 16 which is designed to balance theplatforni 9, whereby a coin of a predetermined denomination and of standard weight will cause the tilting thereof when droppingr from the runway 8 onto the said platform, and after the ysaid coinhasgtraveled forwardly upon the latter within the long leverage'- portion of the said platform, thus permitting the coin to dropinto the vending 'machine for actuating the same. Arranged Within the column '7 spaced below the tilting platform 9 are downwardly, converging guideways 17 which deflect the coin of predetermined denomination and of standard weight intothe machine for the actuation thereof.'

Provided in the front wall of the column 7, at the forward end of the tilting platform 9, is an exit slit 18, which communicates with a catch pocket 19 mounted upon the front wall 5 of the vending machine` casing,

so that should a disklor coin of a weight lighter than the predetermined coin of standard weight be dropped into ythe chute column through the inlet slit 6 therein, the said disk or coin will `gravitate from the runway 8 onto the/tilting platform 9, but will not tilt the same and thence will be delivered through the exit slit 18 into the catch cup 19. In other words, by reason of pivotally mounting the platform 9 on a diagonal axis, it will possess leverage different at opposite ends, and the same will be sus ceptible of quicker tilting action at one end than at the op osite end, so that when a coin of a heavler weight than the redetermined coins of standard weig t vis dropped onto the platform 9 at the short leverage end, it w1ll instantly tiltfor the dropping of the said coin into the compartment 20. Now,'on the falling of the coin of standard weight onto the platform 9, at the short leverage end thereof, the saidy platform will not respond by a tiltin action, until said coin has rolled onto sai end, whence it will tilt, dropping said com into the machine to be o erated. 1 Thus, in this manner, the said com or disk will be ejected from the vending machine, so as to prevent any possibility of the actuation thereof. Should a disk or slug of a heavier weight than the predetermined coin of standard weight be introduced into rthe chute, the same will be caused to gravitate from the runway 8 onto the platform 9 at the end having the shortest leverage, whereupon the platform will be caused to tilt, dropping the slug or disk into a compartment 2O separated from the course of travel of the coin of the predetermined denomination and standard weight by means of a vertical partition 21 inthe chute c'olunin 7, thereby separating the coins .from each other, so that the slugs will be ineffective in operating the vending machine.

What is claimed is:

1. The combination with a coin chute, of

a coin detector, comprising a tilting platform intersecting the path of said chute, and means pivoting the said plat-form on a diagonal axis, whereby said platform will tilt on the Contact of a coin of a predetermined weight therewithl at one end of the same and also on the contact of a coin ofa different weight with respect to said firstnamed coin therewith at its opposite end.

2. The combination with a coin chute, of a coin detector, comprising a tilting platlong leverage form intersecting the path of said chute,

weight therewith atone end o the same andalso on the contact of a coin of a different weight with respect to said first-named coin ltherewith at its Iop osite end, and adjustable weight means or balancing said platform.

I 3. The combination with a coin chute, of a coin detector, comprising a tilt-ing platform intersecting the path of said chute, means pivoting the said platform on a diagonal axis, whereby said platform will tilt on the contact of a coin of a predetermined weight therewith at one end of the same and also on the contact of `a coin of a differ# ent weight with respebt to said first-named coin therewith at its opposite end, adjustable weight means for balancing said platform, and a partit-ion in said chute below the platform to form independent chambers for receiving said coins, respectively.

4. The combination with a coin chute, of a coin detector, comprising a tilting platform intersecting the path of said chute, means pivoting the said platform on a diagonal axis, whereby said platform will tilt on the contact of a coin of a predetermined weight therewith at one end of the same and `also on the Contact of a coin of a different weight with respect to said first-named coin therewith at its opposite end, adjustable weight means for balancing said platform, a partition in said chute below the platform to form independent chambers for receiving said coins, respectively, the said chute being provided with an opening at one end kof the platform, and a cup exteriorly of the chute below the said opening for receiving a coin lighter than the previously mentioned coin.

In testimony whereof I affix my signature in presence of two witnesses.
